Refactoring Project

• The refactoring roadmap is available here
• Planning quarterly, 2-3 day, asynchronous hackathons to focus on work, reviews, etc.

CodeScene and Ruff

• Ruff is setup on SasView, SasData and SasModels.
• Codescene is enabled for SasData using in-repo config files (https://github.com/SasView/sasdata/tree/master/.codescene). The config currently does not trigger any PR checks.
  • Path forward:
    • Need to tweak config to ensure the code is checked, but isn't onerous to developers
    • Look at other projects that use CodeScene and how they use it
    • Need writeup on issues noted by CodeScene: what they mean, why they are an issue, what can trigger the issue, and ways to fix the issue
    • Once sasdata CodeScene is in a helpful state, move config files to both sasmodels and sasview

ADRs

• Sent to the mailing list
  • https://github.com/orgs/SasView/discussions/3245: Dependency Freezing
    • Jeff to write final version and include info on freezing between versions (no changes between bug fixes, small changes for feature revisions, and open for major changes, unless issues found with specific dependency versions), and remove pins when merging release branch into main
  • https://github.com/orgs/SasView/discussions/3170: Type hints - new suggestion to not require them, but PR reviewers should note they are missing, with a suggestion on implementation - Finalize?
  • https://github.com/orgs/SasView/discussions/3583: Revised ADR Process - Finalize?
• Ongoing discussion:
  • https://github.com/orgs/SasView/discussions/3171: Linter
    • Linter would only apply to ruff - send out for review?
    • Codescene work will be separate
  • https://github.com/orgs/SasView/discussions/3503: Citing SasView and Parallel Projects
    • Suggestion from technical meeting on Dec. 12: Generate DOIs for parallel packages (sasmodels and sasdata), have them all under the same Zenodo community (SasView), only have users cite parallel packages if used for scripting (GUI use - cite SasView only)

Help Desk Staffing needs

• Steve is primary and Miguel is secondary for December.
• We have holes in the schedule from January onwards. Anybody willing and able?
